1 Claim. (Cl. 38-66) v This invention relates to padding, and more particularly to a type that is subjected to moisture, heat and pressure, and such as is employed on the rolls of laundry machines and for other purposes. An example of this type of padding is disclosed in my Patent No. 2,947,098, dated August 2, 1960.

One type of padding as used at the present time, is composed of carded asbestos in the form of abat and over which is placed a sheet of gauze. Some of these pads are laminated or are composed of three or more layers, each of which is generally about one-half of an inch lin thickness. The moisture to which a pad of this nature is subjected by the ironing operation, is intended to be dissipated by the heat from the steam chest. However, when there is more or less continuous feed of linen past the ironing roll bea-ring the padding, the absorbed moisture is not dissipated quickly enough, with the result that the padding packs down so that frequent adjustment is required in order to maintain proper pressure on the rolls.

In ironers of the type for which the present padding is intended for use, such as the chest-type flat-work ironer, the padding must be precisely applied in order to obtain the most eicient results, and moreover, the roll size must be uniformly maintained over a long period of time. The padding applied to the roll of this type of ironer must be such as to permit limited packing down, if the diameter of the roll is to be maintained. It is therefore one of the objects of the present invention to provide a padding having means by which its tendency to pack down will be materially retarded, since the portion of the padding next to the roll will be kept dry, and the part of the padding that is outermost also kept dry, the latter result attained by heat reflection.

It is an object of the present invention to provide a padding which will contain a barrier to prevent foreign matter, such as wax used on most ironers, from penetrating the padding and causing it to become hard and losing its resiliency.

It is one of the objects of the invention to provide a padding which shall be largely composed of loose-fibered asbestos, and usually combined with other bers such as those of Daeron, but which will also provide a layer such as a metallic sheet or foil, for an example, aluminum sheet or foil of moisture-impervious, heat-reflecting nature, interposed in the brous material and located between the outer surfaces of the padding. Such a metallic layer will thus form a barrier in the padding and will also serve as a heat reilector tending to reflect heat back through that part of the padding which is interposed between the metallic layer and the surface of the roll that is positioned adjacent to the steam chest. The layer or layers of fibrous material disposed between the metallic sheet or foil and the roll will be kept dry; will not materially pack down7 thus maintaining a uniformly-sized roll; will result in ironing of better quality; will subject the roll covering to less wear and will require fewer adjustments of the roll.

ICC

In my Patent No. 2,947,098 herein mentioned, I have disclosed a padding meeting the above requirements, and

the present invention relates to an improvement 'on the g padding therein described, and has particular reference to means by which the layer of metallic foil is maintained in the bat of vasbestos fibers. It is therefore one of fthe objects of the present invention to provide means vby which the several layers of the padding are maintained in their desired relation; to provide means by which compacting of parts of the brous layers along the marginal edges of said layers will tend to cause interengagement or intermingling of the fibers of the asbestos in such a manner as to lock in the metallic layer and lmaintain the same against lateral shifting.

With these and other objects to be hereinafter lset forth in view, I have devised the arrangement of parts .and method steps to be described and more particularly pointed out in the claim appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of the invention is disclosed,

Fig. 1 is a face view, with some of the layers shown fragmentarily, of a section -of padding for laundry rolls, made in accordance with the invention;

Fig. 2 is a sectional view, taken substantially on the line 2-2 of Fig. 1,* looking in the direction vof the arrows;

Fig. 3 isy a sectional View, taken substantially on the line 3--3 of Fig. l, looking in the direction of the arrows; and

Fig. 4 is a sectional view, in perspective of a portion of the padding. Y

In the embodiment of the invention illustrated in the drawing, the pad or padding may be composed of a number of layers, such as for example, four layers, those indicated at 1, 2 and 3 being preferably composed of librous, heat-resistant material, such as carded or felted asbestos, possibly mixed with other fibers, such as Daeron iibers. form thickness, being preferably one-half inch in thickness, although this thickness might be varied considerably. 'I'he fibers of the material are relatively loose, but the same possess a natural tendency to adherently unite particularly under pressure.

The layers shown at 4 is composed of flexible, moistureimpervious, heat-reflecting metallic sheeting or foil, such as aluminum sheet or foil, preferably ranging from .0007

to .001 in thickness, more or less.

The layer or foil 4 of aluminum is sandwiched between the fibrous layers and in the embodiment shown it is preferably located in the resultant bat closer to one surface than to the opposite face of the padding. For example, in the embodiment shown in Fig. Z, the metallic foil is arranged closer to the surface S than it is to As will be apparent from Fig. l, the metallic vfoil layer 4 is made of less width than the width of the asbestos layers 1, 2 and 3, with the result that the opposite longitudinal edges 7 and 8 of the metallic foil are located inwardly of the adjacent longitudinal edges 11 and 12 of the asbestos material. This results in the production of the marginal edge parts 9 and 10.of the asebstos materiaLy which parts extend laterally beyoiid the edges 7 and 8 These projecting portions 9 and 10 constitute sealing or enclosing means for the foil and Y of the metallic foil.

they operate in a manner to restrain the foil against lateral These three layers may be more or less of uni- 3 shift relatively to the body of the bat, or to at least greatly minimize its lateral displacement.

When pressure is imposed on the padding, either during the ironing operation or prior thereto, with such pressure emphasized if necessary, on the marginal edge parts 9 and 10 of the asbestos, these parts of the asbestos will be caused to have their relatively loose bers so compacted, intermingled, and interengaged and matted together that these portions of the padding will become substantially closed, thus sealing in edge portions of the metallic foil, with the three or more layers of the asbestos becoming consolidated into a more or less unitary thick bat in the areas indicated at 13. In compressing the edge portions of the brous layers, it is essential that the amount of pressure applied shall be relatively light so that it will not materially decrease the thickness or soft ness and compressibility of these edge portions.

With the arrangement described, a heat and moisture barrier is introduced in the pad between the layers thereof. This barrier, consisting of the metallic sheet 4, allows the moisture to enter into the portion of the pad next to the steam chest, or that asebstos layer indicated at 1 and described as the outer layer. The heat-reilecting characteristics of the metallic sheet cause the heat to be reected back, thus tending to dry the layer 1 while keeping the layers 2 and 3 relatively dry by its moisture-impervious quality. By keeping the layers 2 and 3 dry the compacting of these layers is prevented, the resilience of the pad is maintained and numerous other advantages are secured as will be apparent to those skilled in this art. Among such advantages is the prevention of foreign matter, including wax, from compacting and accumulating in the pad to cause hardening of the same.

The addition of the metallic layer to the pad adds considerable strength and body to it, permitting the pad to be more easily applied and handled, and in addition it materially extends the life of the pad.

It is herein stated that the padding might consist of three layers of asbestos fibres with an interposed sheet of metallic or aluminum foil. This may be varied to suit diierent ironing requirements.

Having thus described a single embodiment of the invention, it is obvious that the sarne is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claim.

What I claim is:

A padding for laundry rolls comprising, a plurality of layers of brous material, a layer of metallic foil sandwiched between the layers of brous material, the side edges of the metallic foil terminating inwardly of the side edges of the layers of fibrous material to thereby cause marginal edge portions of the top and bottom layers of fibrous material to project beyond the side edges of the metallic foil, said projecting marginal edge portions of the fibrous material being sufficiently compressed together to cause the matted relationship of their fibres thereby without materially decreasing the thickness or the compressibility of the layers of fibrous material and to cause said marginal edge portions to form enclosing means for the metallic foil to hold the same against shifting.
